10Gbps adaptive rate full-rate clock recovery CDR 2/4 frequency division
The U9710A/B 10Gbps adaptive rate full-rate clock recovery instrument is a testing device that can automatically adapt the input signal rate within the range of 10Gbps and below, and recover a clock signal synchronized with the signal to be tested.
Adaptive rate
It supports a rate range of 1.25Gbps to 10.3125Gbps and can automatically adapt to the rate of the input signal without manual configuration.
Full-rate clock recovery
It can restore the full-rate clock signal synchronized with the signal to be tested, providing a stable trigger clock for the test equipment.

Application scenarios
Optical network equipment testing
In the testing of optical network equipment, such as ONT testing or line board card testing, when the signal to be tested only has an optical signal output but no clock output, a clock recovery instrument can be used to recover the clock signal, which is then used to trigger the sampling oscilloscope for eye diagram testing.
High-speed communication module test
It is used for testing parameters such as the emission eye diagram and jitter tolerance limit of 10Gbps optical modules (such as XFP, SFP+).
Research and development of data centers and network equipment
During the research and development process of data centers and network equipment, the 10G interface performance of the equipment is verified to ensure its reliability in high-speed data transmission.
